| 摘 要： | 冷轧板喷涂表面在生产过程中有许多表面质量缺陷,如表面缩孔缺陷,严重制约冷轧板喷涂的品质和制造成本.为了是提高冷轧板喷涂表面质量,本文运用FTA方法（故障树分析方法）,分析某家电外箱体冷轧板喷涂生产过程中形成表面缩孔缺陷的原因,绘制故障树,进行布尔代数计算求出最小割集,提出部分优化措施,最终提升该系列产品的市场竞争力,并为进一步研究提供帮助.

| Abstract: | During the sheet steel powder coating process,there are many surface quality defects,such as the surface of shrinkage cavity problem,which seriously affect the sheet steel surface quality of powder coating and manufacturing costs.The study aims to improve the sheet steel surface quality of powder coating.This paper employs FTA method to analyze the causes of the surface of shrinkage cavity problem about a household appliance sheet steel box,to draw fault tree,to compute the minimal cut-sets by Boolean algebra and to propose some optimized measures.Finally,the conclusions can be applied to enhance the products market competition,and to expand this future research. |
